RAILROAD-TIE.

Specification of Letters Patent. Application filed May 21 Patented Sept.7, 1909. 1999. {Serial No. 497,384.

To all whom it may concern: 1 y j Be it known that I, RUFUS R. CANrmLD,a citizen of the United States, residing at Clearfield, in the county ofClearfield and State of Pennsylvania, have invented a new, and usefulRailroad-Tie, of which the fol lowing is a specification. I i

It is the object of the present invention to' provide an improvedconstruction of rail-: way tie and the invention relates more spe-'cifically to that class of railway ties which; are metallic and whichhave rail clamping members readily engageable with and -disengageablefrom a rail supported upon the tie, and the object of the invention isto simplify the construction of such tieand yet provide rail clampingmeans which will firmly lock the rail against lateral displace-v ment.

It is a further object of the invention to provide, in a tie of theclass described, rail clamping means having a resilient or otherwiseyieldable portion and to provide means .or cooperation with such portionto cause the rail engaging portion of theclampinm means to bind firmlyagainst a rail disposed upon the tie. I

The invention further aims in this con-. nection, to provide a means forcoo eration clamp-' mg means which will automatically. look when movedto position to cause the saidi clamping, means to bind against a railupon with the resilient portion of the rai the tie.

A still further object of the invention is to provide means which maybereadily assembled with the tie to clamp a rail thereon in the event offracture of the integral or permanent rail clamping or engaging permeansbeing clamped in position through the medium of the-means whichcooperate with the resilient portion.

tions of the tie, such of the rail clamping member above referred to. V

Fig. 6is a view similar toFig. 1 but showingthe on the line 33 'of Fig. 4 is adetail perspectiveview repair. device assembled with the tie, and Fig. 7is a detail perspective view of the repair device.

Referring more specifically'to Figs. 1 to 5 inclusive of the drawings,the tie is shown as having its intermediate or body portion ofsubstantially the same cross-sectional conp upon the rail supportinghead 11, there being a thin block of wood or other yieldable material 15disposed between the rail and the said upper face of the head 11, theupper face being recessed as at 16 to receive the said bloc The upperwall of the rail supporting head 11, above referred to, is formed with aslot 17 which extends in a direction longitudinally of the head andthrough which pro jects the head 18 of a rail clamping member includingalso a resilient shank 19 which extends beneath the top wall 13 of thehead and outwardly and slightly beyond the outer end of the head. Thehead 18 of this clamping member is formed with a lip 20 which engageswith the inner base flange of a rail disposed upon the block 15 and itwill be 1 stem 21, a cam portion 22, and a head 23 which is preferablyof the same general shape as the cam portion 22 and is spaced therefromand presented endwise toward the same. One side wall of'the railsupporting head 11 of the tie is formed with a slot 24: which is of suchsize as to permit of passage of the stem 21 and the cam portion 22therefon,'the end of the stem seating in the opening or seat 25 formedin the opposite side wall of the rail supporting head as is clearlyshown in Fig. 3 of the drawings, it being understood that the key is inthis manner so supported as to permit of rotation. .The

cam portion 22 of the key and the head 23 thereof are spaced apart adistance equal to the thickness of that side wall of the head throughwhich the slot 24 is formed so that when the key is in the positionshown in Fig. 3 of the drawings, the cam portion 22 will lie between thesaid side walls of the head and the head 23 will lie outwardly of thatside wall through which the slot 24 is formed. The shank 19 of the railclamping member is formed in its upper face with a longitudinallyextending rib 26 having a notch 27 therein and upon rotating the lockingkey 21 from a position in which it is inserted through the slot'2a, tothe position shown in Figs. 1 and3 of the drawings, the cam portion 22of this key will ride over the rib 26 upon the upper face of theresilient shank 19 of the rail clamping member and will finally seat inthe notch 27 in the said rib, the key being in this manner lockedagainst further rotation, accidentally, in either direction.

The fact will readily be appreciated, from an inspection of Fig. 3 ofthe drawings that when the key is in position just described, 7

the opposing ends of its stem portion 22 and head 23 will engage withopposite faces of the side wall of the head through which the slot 2& isformed and that consequently withdrawal of the key without disengagingit from the notch 27 is rendered impossible.

Furth ei'niorefihe resilient shank 19 of the rail clamping member isresilient only to such degree as will necessitate the exertion ofconsiderable force in rotating the key to the position in Figs. 1 and 3of the drawings, and, in a like manner, considerable force will berequired to be exerted to rotate the key from this position.

It will of course be understood that when the key is rotated toposit-ion to disengage from the resilient shank of the rail clampingmember, the head end of this member may be readily depressed by graspingits shank end and raising the said shank end and that in this manner themember may be disengaged from the rail and removed bodily from the boss.7

In the form of the invention shown in Figs. '6 and 7 of the drawingsthere is provided means whereby a rail upon the tie may be firmly heldthereon in the event of fractureof the integral rail engaging portion 1L of the rail supporting head and to this end, the top wall 13 of theboss is formed, outwai'dly of the rail supporting portion and beside therail engaging portion 14, with a slot 28 through which, in event ofinjury to the rail as stated, the head 29 of a rail engaging member isinserted, said head being formed for engagement with the outer baseflange of a rail upon the tie. This member comprises, in addition to thehead 29, a shank 30 which, when the member is in position upon the head11 of the tie, extends beneath the top wall 13 thereof as is clearlyshown in Fig. 6 of the drawings and this shank 30 is formed in its undersurface with a notch 31 in which the upper side of the stem 21 of thelocking key of the rail engages, its cam portion 22 engaging the notchin the resilient shank of the first described rail clamping member asheretofore observed.

While the last described clamping member is designed primarily for usein the repair of the tie embodying the present invention, it will bereadily understood that it may be 'empl-oyed in conjunction with therail engaging portions lt of the rail supporting heads of the ties, atswitches and other points where the rails are liable to be subjected toconsiderable lateral stress and that therefore its use is not limited torepairing broken rails.

The under side of the tie is formed, prefe'rably throughout its entireextent, with transverse ribs 32 which dig into the roadbed and serve toprevent displacement of the ties as will be readily understood.

It is preferable that a key 33 be inserted between the portion 14.- andthe outer edge of the base flange of the rail and that this key bewedge-shaped whereby the rail may be forced in the direction of thecenter of the track way should the rails become spread to anyappreciable degree.

What is claimed is 1. A tie having a rail engaging head thereon, thesaid head being formed with :1 slot through its rail supporting portion,a rail clamping member having a head projecting through the slot andhaving a resilient shank, and cam means upon the tie movable to positionto depress said shank and thereby cause the head to bind against therail upon the tie.

2. A tie having a rail engaging head thereon, the said head being formedwith a slot through its rail supporting portion, a rail clamping memberhaving a head projec-ting through the slot and having a resilientshank,and a cam key upon the tie movable to position to depress said shank andthereby cause the head to bind against a rail upon the tie.

3. A tie having a rail engaging head thereon, the said head being formedwith a. slot through its rail supporting portion, a rail clamping memberhaving a head projecting through the slot and having a resilient shank,and a rotatable cam key carried by the tie and movable to position todepress said shank and thereby cause the head to bind against a railupon the tie.

4;. A tie having a rail engaging head thereon, the saidh-ead beingformed with a slot through its rail supporting portion, a rail clampingmember having a head proporting jecting through the slot and having aresilient shank, the said head being formed through one side wall with aslot, a cam key inserted through the slot in the side wall of the headand rotatable to position to depress the said shank and thereby causethe head to bind against a rail upon the tie, the cam portion of the keyengaging with the said side wall of the head whereby to obviatedisplacement of the key.

5. A tie having a rail engaging head thereon, the said head being formedwith a slot through its rail supporting portion, a rail clamping memberhaving a head projecting through the slot and having a resilient shank,one side wall of the head being formed with a slot, and a cam lockingkey inserted through the slot in the said side wall of the head andhaving a head and a cam portion spaced from the head and engaging withthe shank whereby to depress the same and thereby cause the head to bindagainst a rail upon the tie, when the key is rotated to one position,the said cam portion and head of the key engaging upon opposite faces ofthe said side wall of the head when in such position whereby toobviatedisplacement of the key.

6. A tie having a rail engaging head thereon, the said head being formedwith a slot through its rail supporting portion, a rail clamping memberhaving a head projecting through the slot and having a resilient shank,the said shank being formed with a notch, and cam means upon the tiemovable to position to depress said. shank and thereby cause the head tobind against a rail upon the tie, the said cam means engaging in thesaid notch in the shank.

7. A tie having a rail engaging head thereon, the said head being hollowand being formed with a slot through its rail supportion, a railclamping member having a head projecting through the slot and aresilient shank extending into the said head, and a cam key extendinginteriorly of the head and movable to position to depress said shank andthereby cause the head to bind against a rail upon the tie.

8. As a repair means for a tie having an integral rail engaging head,the said tie being formed with a slot, a rail clamping member having ahead projecting through the slot and engaging with a rail upon the tieand having a resilient shank, a second rail clamping member having alsoa head engaging with the rail upon the tie and having a shank underlyingthe rail supporting portion of the tie, and a locking member extendingbetween the shanks of the two rail clamping members and movable toposition to bind the shank of the last mentioned member against the saidunder side of the rail supporting portion of the tie and depress theshank of the first mentioned rail engaging member whereby to cause thehead of the same to bind against the rail.

. 9.
